President-elect Donald Trump has undoubtedly ruffled feathers in staffing his administration, but the choice of Robert F. Kennedy, Jr. — know for his skepticism on the safety of vaccines — to chair a commission tasked with studying the efficacy of and issues concerning vaccinations, will undoubtedly raise eyebrows from both sides of the issue.

Kennedy, according toUSA Today, will chair the presidential commission “to make sure we have scientific integrity in the vaccine process for efficacy and safety effects,” the environmental activist and politician told reporters after meeting with Trump on Tuesday.

Kennedy noted the incoming president requested the meeting, as he “has some doubts about the current vaccine policies and he has questions about it. His opinion doesn’t matter, but the science does matter and we ought to be reading the science and we ought to be debating the science.”

While advocates of the heavy vaccination schedule might find the choice of Kennedy — who has been castigated as an anti-vaxxer — quite startling, he insisted Trump remains “very pro-vaccine, as am I,” and only seeks to ensure “they’re as safe as they can possibly be.”
